Descrizione dettagliata dell'Invenzione Detailed description of the invention
La presente invenzione concerne un inserto in gommapiuma costituita da poliuretano espanso a cellule aperte che in corrispondenza della zona del tallone (3) ha una densità più elevata rispetto alla zona della pianta e dell’arco plantare (4), inserito in un fondo bi-materiale per calzature il cui primo strato (1) direttamente a contatto con il terreno à ̈ in TPU, o cuoio od altro materiale, mentre il secondo strato (2), sovrapposto a detto primo strato (1) battistrada, à ̈ in PU , o cuoio od altro materiale, con un film in PVC (6) secondo una preferita - ma non limitativa - forma di esecuzione. The present invention relates to a foam insert consisting of open cell polyurethane foam which in correspondence with the heel area (3) has a higher density than the plantar and arch area (4), inserted in a bi -material for footwear whose first layer (1) directly in contact with the ground is in TPU, or leather or other material, while the second layer (2), superimposed on said first layer (1) tread, is in PU , or leather or other material, with a PVC film (6) according to a preferred - but not limiting - embodiment.
La valenza distintiva dell’invenzione à ̈ data dalla morbidezza dell’inserto di poliuretano espanso a cellule aperte che ha una densità che varia dai 50 Kg/m<3>ai 75 Kg/m<3>in corrispondenza della zona della pianta e dell’arco plantare (4) e dai 95 Kg/m<3>ai 120 Kg/m<3>in corrispondenza della zona del tallone (3) per evitare che il piede, in corrispondenza del tallone, affondi eccessivamente. Detto poliuretano espanso a cellule aperte à ̈ un materiale molto morbido, con effetto memory simile ad un materasso di gommapiuma, con costi notevolmente contenuti. The distinctive value of the invention is given by the softness of the open cell polyurethane foam insert which has a density ranging from 50 Kg / m <3> to 75 Kg / m <3> in correspondence with the plant area. and of the plantar arch (4) and from 95 Kg / m <3> to 120 Kg / m <3> in correspondence with the heel area (3) to prevent the foot from sinking excessively at the heel. Said open cell polyurethane foam is a very soft material, with a memory effect similar to a foam rubber mattress, with remarkably low costs.
La resistenza e consistenza del poliuretano espanso a cellule aperte varia in funzione delle esigenze realizzative e a seconda di quale grado di morbidezza dell’inserto si vuole ottenere. The resistance and consistency of open cell polyurethane foam varies according to the manufacturing requirements and according to what degree of softness of the insert is to be obtained.
Una ulteriore modalità realizzativa prevede l’utilizzo di un inserto in gommapiuma costituita da poliuretano espanso a cellule aperte di un’unica densità sia per la zona del tallone (3) che per la zona della pianta e dell’arco plantare (4). A further construction method involves the use of a foam insert made of open cell polyurethane foam of a single density both for the heel area (3) and for the plantar and arch area (4 ).
La schiuma poliuretanica a cellule aperte può essere colata all’interno del fondo bi-materiale della calzatura al di sopra dello strato (2) in PU e penetrare sino all’interno dei fori (5) ricavati sulla superficie perimetrale di detto strato (2) in PU in modo che detti fori (5) costituiscano per detta schiuma poliuretanica un sistema di bloccaggio che avviene quando, tramite una reazione chimica nota in seguito alla sua colata, la schiuma poliuretanica diventa poliuretano espanso a cellule aperte comunemente chiamato gommapiuma o gommaschiuma in quanto il risultato di detta reazione nota à ̈ un materiale spugnoso; oppure detta schiuma poliuretanica può essere preformata ed inserita a seconda dell’utilizzo specifico. The open cell polyurethane foam can be poured into the bi-material bottom of the shoe above the PU layer (2) and penetrate up to the inside of the holes (5) made on the perimeter surface of said layer ( 2) in PU so that said holes (5) constitute for said polyurethane foam a locking system which occurs when, through a known chemical reaction following its casting, the polyurethane foam becomes open cell expanded polyurethane commonly called foam rubber or foam rubber since the result of said known reaction is a spongy material; or said polyurethane foam can be preformed and inserted according to the specific use.
Detta gommapiuma presenta uno spessore maggiore in corrispondenza della zona del tallone (3) per diminuire gradualmente di spessore in corrispondenza della zona della pianta e dell’arco plantare (4), in modo che si abbia la percezione di camminare su un materasso di gommapiuma che si adatti all’anatomia fisiologica del piede. Said foam has a greater thickness in correspondence of the heel area (3) to gradually decrease in thickness in correspondence of the plantar area and arch (4), so that one has the perception of walking on a foam rubber mattress that adapts to the physiological anatomy of the foot.
L’utilizzo di detta gommapiuma favorisce una riduzione della pressione e delle tensioni del corpo, migliorando la circolazione venosa e garantendo una piacevole sensazione fisica ed un aumento del comfort della persona. The use of said foam promotes a reduction in pressure and body tensions, improving venous circulation and ensuring a pleasant physical sensation and an increase in the comfort of the person.
Inoltre detta gommapiuma mantiene la sua morbidezza nonostante varino le condizioni climatiche da umido a secco e viceversa. In addition, said foam retains its softness despite varying climatic conditions from wet to dry and vice versa.
Detto materiale ha anche la caratteristica di essere vibroassorbente ed anallergico e possiede una buona durabilità meccanica (Memory Effect). La sua densa struttura, inoltre, impedisce all’acqua di penetrare rendendolo impermeabile, essendo tuttavia in grado di assorbire e lasciare traspirare l’umidità in modo da mantenere le parti a contatto con esso ad una temperatura corporea ideale. Said material also has the characteristic of being vibro-absorbent and hypoallergenic and has a good mechanical durability (Memory Effect). Furthermore, its dense structure prevents water from penetrating making it waterproof, however it is able to absorb and let moisture transpire in order to keep the parts in contact with it at an ideal body temperature.
Secondo la preferita - ma non limitativa - forma di esecuzione dell’invenzione sopra esposta, sopra a detto inserto in gommapiuma, per far sì che il piede non vada direttamente a contatto con esso, à ̈ presente una suoletta di montaggio biodegradabile e perforata nella sua intera lunghezza, in modo da permettere il ricircolo dell’aria all’interno della calzatura. Grazie alla pressione che si ha durante la deambulazione, si ha l’effetto di eliminare la sudorazione del piede. Sopra a detta suoletta biodegradabile à ̈ presente un footbed anatomico di latex con punti strategici nella zona plantare e del metatarso che influiscono direttamente, tramite pressione, dalla pianta del piede sui vari punti dell’organismo, rendendo l’appoggio adeguato alla fisiologia del piede sia in una posizione statica che dinamica. According to the preferred - but not limiting - embodiment of the invention described above, above said foam insert, in order to ensure that the foot does not come into direct contact with it, there is a biodegradable and perforated mounting insole. in its entire length, in order to allow the recirculation of air inside the shoe. Thanks to the pressure that occurs during walking, it has the effect of eliminating the sweating of the foot. Above said biodegradable insole there is an anatomical latex footbed with strategic points in the plantar and metatarsal area that directly influence, through pressure, from the sole of the foot on the various points of the body, making the support suitable for the physiology of the foot in both a static and dynamic position.
I materiali e le dimensioni dell’inserto trovato in poliuretano espanso a cellule aperte come sopra descritto, illustrato negli uniti disegni e più avanti rivendicato, potranno essere qualsiasi a seconda delle esigenze. Inoltre tutti i dettagli sono sostituibili con altri tecnicamente equivalenti, senza per questo uscire dall’ambito protettivo della presente domanda di brevetto. The materials and dimensions of the insert found in open cell polyurethane foam as described above, illustrated in the accompanying drawings and hereafter claimed, may be any according to requirements. Furthermore, all the details can be replaced with other technically equivalent ones, without thereby departing from the protective scope of the present patent application.
